This is my first year growing veggies and it's been a learning experience which would take way too long to get into. I read someone's posting in Plant Talk about how high some of their tomato plants are growing and I'm facing the same challenge. My Brandywine toms just keep growing. They're at least 7ft at this point. The problem is they are getting so heavy that a couple of them are crumpling under the weight. I came home one day this week only to find the whole thing on the ground. It was very sad as I lost a number of branches that had all sorts of little tomatoes on them. I used a 6 ft stake to keep this one up. I have a couple of the circular metal ones on the others, but they're not really high enough. Any words of wisdom on how to stake these indeterminate guys?
